Cathode active materials startup ACT-ion raises $7.5 million in funding round
Battery cathode active materials (CAM) startup ACT-ion Battery Technologies has raised $7.5 million in a pre-Series A funding round. The $7.5-million round was led by BASF Venture Capital and included participation from Hunt Energy Enterprises, Mirae Asset Capital, Arosa Capital Management and LG Technology Ventures. ACT-ion will use the proceeds to accelerate its CAM production… Read more »
Why are so many Western battery startups failing?
The US and Europe badly need to start manufacturing battery cells, and break the Chinese dominance of the market. But there’s no joy in Batteryville these days—once-promising startups are failing and/or scaling back their plans. Northvolt, a European company that was founded in 2017, and raised over $13 billion, has struggled for two years to… Read more »
A closer look at Li-ion dry electrode coating technology
The dry electrode coating process has the potential to enable the production of better, greener, more cost-effective batteries. It relies on advanced fluoropolymer binders with Teflon™ For a few years now, Charged has been reporting on how dry electrode coating processes have the potential to revolutionize battery production by eliminating the use of hazardous, environmentally… Read more »
What’s in a name? Mercedes-Benz announces new EV naming conventions
“What’s in a name? That which we call a rose by any other name would smell as sweet.” Those words, spoken by Juliet in Shakespeare’s great tragedy “Romeo and Juliet,” imply that names are meaningless. But don’t tell a product manager that, especially one in the automotive industry. Car names follow trends in culture and… Read more »
Factorial develops Solstice solid-state battery with customer Mercedes-Benz
Factorial has launched an all-solid-state battery developed with customer Mercedes-Benz to extend EV driving range. Solstice incorporates a dry cathode design for more efficient production. It delivers specific energy of up to 450 Wh/kg while reducing vehicle weight and increasing efficiency, which can extend EV range by up to 80%, according to the company. The… Read more »
Renewable energy sources for off-grid EV charging
In the previous article on off-grid EV charging, the focus was on the energy storage battery and the DC-AC inverter that supplies the EV charger (and all of the other AC loads). This time the focus will be on the renewable energy sources themselves. For reasons of practicality (and availability) the emphasis will be on… Read more »
Smart 3D scanning and inspection for EV battery manufacturing
Sponsored by LMI Technologies. As the world races towards a future powered by sustainable energy solutions, electric vehicles have emerged as a pivotal technology in reducing carbon emissions and reliance on fossil fuels. Central to the viability and safety of EVs are their battery systems, which demand meticulous inspection and quality control. LMI Technologies, a… Read more »
Aqua Metals is building a more sustainable battery recycling ecosystem
Q&A with Aqua Metals execs Steve Cotton and David Regan Regardless of the claims made in Facebook memes, Li-ion batteries are eminently recyclable, and current recycling methods cause far less environmental damage than the well-documented depredations of the petroleum industry. However, as sustainability is central to the mission of the EV industry, we need to… Read more »
Webinar: Meet vehicle requirements through optimized battery cell design
Battery cell design optimization is intricate, involving a multitude of design parameters such as cell geometry, electrode micro-structure, and materials properties. These parameters often have conflicting effects on key requirements. For example, increasing electrode thickness can enhance energy density but may come at the expense of fast-charge capability. In this 60-minute webinar, Xavier Conqui and… Read more »
